well I have a single BTL18 now and was wondering the smallest box that 2 could fit in or if I might want to look at 2 15's. I have 36X30 for a box now and wondering how tall I would need to make it to fit either 1 more 18 or 2 15's also would like the tuneing around 35. If someone can help with this it would shure help. Thanks

Hey i just wanted to know what would be a good enclosure for SPL with 2 12" BTLs.... I Drive a 2003 Tiburon GT and do wanna be able to listen to music occasionally. Thanks for the help

Ok guys heres the situation. I ordered a BL 15 with cooling and flat wind dual 2 ohm. I'm building a box myself and having trouble on what to do with the port. The box is planned at 3.76 ft^3 with the woofer displacement added in. Its recommended to have 12-16 sq in of port per cube so i need anywhere from 45-60 sq in of port. I want to just maybe slap a 3x6 aero port or maybe a 4x6 aero port. The 3x6 is 42 sq in and the 4x6 is 75. Both not in the range i need. Also looked on amazon and found precision ports 3 in and a 4 in round. Doesn't say the length on them tho . Reviews say there adjustable somehow. Help would be appreciated. Also wanted some recommendations on ampl…

So I am trying to decide on which Fi.Q I want... Either the 10 or the 12. My plan is to build a custom sealed enclosure to sit in between the second row captains chairs in my Tahoe, and the sub will down fire. I am leaning more toward the 10 because of space constraints... the maximum size enclosure I can fit in there is 27" L X 14" W X 10" H... So would y'all recommend the 10 or 12 with that, and what cubic footage for the enclosure? Also, What amps would pair well with the Fi? I listen to some rap, but mainly mashups, EDM, and lots of rock/country (basically everything hahaha) Side question... I don't know if any of y'all have a Tahoe with the Bose upgraded sound…

hello guys I have two Q15's in a dual chambered slot port box tuned to 27hz @ 8cuft. My question is will it be better to build another enclosure where the drivers share the same chamber? And should I double baffle it? Also, what about bracing? How do I go about doing it? I tuned low because I want the ground pounding bass that you get from the lows as I don't really play anything above 45hz. Thanks.

Was wondering when Fi will have them posted here. Also, does anyone have any for 1 15" BTL @ about 3.5cf with a slot port?

i know you guys are buisy and all but i have been trying to get information on gettin my 18'' BL either warranty or a recone because one of the voice coils only works sometimes. but i have a competition coming up in a couple weeks and i really need this sub fixed in order to get the points i need to go to state finals.

I was wondering if the specs are close enough between the two subs , that can I use my old box (really not old, 3 months) to house my new Fi 18 inch BTL Sub.

Hi, i wanted to know which of these two amps would be better for a bl 18... SAZ-1500d or an SAE-1000D

Whaaat happened? you guys just ruined my next setup :(:( will there be any 15 bls coming?

Hello everyone. I am receiving a 12 inch Q for Christmas which I am rather pleased about because Fi woofers are class... I was wondering what I should do about a box, the woofer is going in my bedroom instead of a car but all the reviews I have read about the Q lead me to it. It will be used entirely for music, rock, techno, a little pop, and perhaps some rap to show off a little. The room is about 8x10x8 with a chunk removed that is about a 18 inches by 3 feet for a closet, so not a terribly large room. One of my questions is the great sealed vs ported debate, which would sound better in this application. The Q will be more than plenty in a room this size either way. I…

Got my bl today, went to bolt it into the box and noticed that the holes in the gasket don't go all the way through. I can see the holes on the bottom then the lip that comes off of the surround goes over the whole and blocks it. Do i drill through it?

scott ive been trying to email you about cutout sheet for box you designed me and i havent heard a from you so i guess ill try on here and this is the email you sent me with the box specs so it should be easy for you to help me out and its for the box with the sub up and port back thanks From: "Sales Fi Car Audio" <[email protected]> To: "jamal martells" <[email protected]> Subject: Re: box question Date: Sat, 9 Jun 2007 13:49:56 -0700 Im assuming it is for a 15" sub given that it is 3.5 cuft. From the dimension the only way to fit the sub is firing up. I will give you designs for both rear and up firing ports... you can choose which works best …

I am trying to construct a ported box for the driver’s console of a 2007 Malibu VLX wakeboard boat. I would like to install an Fi BL12 and push it with a Kicker 1000.1 amplifier in 2 ohms. The dimensions of the box I plan to build are as follows 18” wide x 18” deep x 18.5” high. I am going to use a PSP (Precison Sound Products) port tuned to 32hz. Is this box size adequate for this sub? Will this sub be ok in this environment? (ie. 100% humidity, maybe a few drops of water and a little bit of full sun). Any tips and advice would be much appreciated. I am use to building only sealed boxes, so ports are totally unfamiliar territory for me, but I’m willing to learn. T…

Hey scott. I am Using the hybrid SX woofer in a friends dodge quad truck console.....reatatching the factory console top back to it. I am not sure if i can squezze the needed area out to get enough air space for a ported enclosure. I will be using a eD nine.1 for the power to the woofer...the woofer is D2 and a 12"....Will the woofer perfrom well in a sealed enclsore? also what kind cubic footage do I need? Also do you happen to know off hand the displacement of the woofer? thanks carl

i sent you an email regarding a technical aspect of the BTL. its regarding info on if there is a way to physically measure the gap on a btl motor to identify a SPL motor from a Daily gapped motor. i talked to Nick about this issue, but after being convinced that my btl was a daily gapped motor...i now am doubting it. i took the woofer out of the box today and the sound it makes is just so mechanical metallic sounding on music. this to me would suggest a spl gapped motor. this motor originally belonged to kenny pollock and he said the SPL and daily option were not available at the time when this motor was made. however, it does have all the other options on it (fully loade…

I have a excursion w/2 -18 Q's and want to know if i can tune them to 30hz instead of 28hz? and should i have the port and subs firing to the rear or facing up? all my boxes always had the port and sub on the same side.I would face them to the rear. I would face my box up and the bass cuts in half. Will this do same if i face the subs up and the port to the rear? I want to get the most that i can get out of subs and box. Any input....

Hey i Tested the coils it came back one was .7 normal and one read 0 no idea why its just one but thats what happen so i was wondering shipping from 77632 to yall and back total cost if its a recone that is! Thanks, Teddy

These questions may have been answered before but a quick search did not turn up the obvious answers. I have 2 completely separate and very specific applications I'm looking at for 12" drivers (neither of which involve being inside a vehicle BTW) and I need a little bit more information to help in the decision making process. What is the motor OD on the Q series and the BTL (11.5" I think?) What is the overall depth of the 12" version of the Q and BTL? Also what is the motor only depth of both from the back of the frame? What is the generic xmech of both series? It's nearly the same I assume as baskets, vc od and suspensions are very similar. I figure about 35-36mm inwa…

Right now I'm in the middle of my build with 2 18" BL's with a Trutech Hammer H1 per sub in a 16cuft wall tuned to 30hz. After this I'm pondering changing to two BTL 18's with a DDZ1. Just wondering would it be worth it in terms of being a major leap over the BL's and the Hammers ?

alright so my question is what size and what would be the ideal tuning for a box in my truck. I mostly play a mix of rock and rap So what would u guys suggest would sound best i have a little over 11 cu ft but dont mind doing smaller just want would be best for my music So i guess im going for LSQ i have had no experience with 18s so any help would be apprciated

Ok. i am planning on getting 2 15'' Bl's. (Dual 1 ohm, cooling, and flatwind). How much power can i feed them without buring them up?

how long are Q voice coils?
